@Taekook_guards if I remember correctly, yes he did. To him it was just another random killing cause he has no emotions so he didn't think anything about it until Roha & now he is slowly starting to feel and know that he has hurt Roha deeply.
@Bangtanlena ok then I really want him to apologise sincerely and remorse instead of going forward with his emotionally fuc*** up mind. (But deep down i wanted to see he didn't kill Roha's mother 😭)
@Taekook_guards yes he killed her but it's because he was abused by her when he was young. You can see how he described her as his mother and his "first woman". And though he doesn't yet feel bad about killing MC's mother, he does regret that the act hurt MC and he believes that, in time, he will feel guilt for all the wrong things he did in the past.
